Any camper groups on Hawaii Island?

HAWAIIANTAB

Would like to network with a small group of campers with similar interests and not only limited to Tabs as the public campgrounds are so camp unfriendly. I do have a couple of private owned land sites [including my own in the rain forests] and maybe others have access and could share? Looking at land in Kalapana where there are no rules, or they are not enforced [for now]. 
Please post if you're interested and/or PM.
